"A sophisticated health monitor that still requires total commitment to the Apple ecosystem."
The watch analyzes pulse wave velocity and overnight breathing patterns using its optical sensors to flag potential signs of chronic hypertension or sleep apnea, which are intended to prompt a consultation with a doctor, not self-diagnose.
This is for the iPhone owner who prioritizes passive, cutting-edge health monitoring and is willing to trade battery longevity for continuous data. The value is strong for those already embedded in Apple's ecosystem and interested in the new hypertension and sleep apnea flags.
Android users should not consider this, as it will not function. Anyone who requires multi-day battery life for travel, endurance sports, or simple convenience will be frustrated. A Garmin or Fitbit provides core fitness tracking with far greater stamina and cross-platform support.
